摘要/Abstract

摘要： 依据实际Φ120 mm圆坯水平连铸过程中15 t中间包原型,采用模型与原型之间1:1.5的相似比建立了水模拟系统,对原型中间包内钢液的流场进行了评估,并研究了中间包控流装置对中间包内钢液流动特性影响。结果表明,使用湍流控制器能显著降低中间包中死区比例,但对最小停留时间延长有限;使用导流槽和低坝显著延长钢水在中间包内停留时间,促进夹杂物上浮。

Abstract: According to actual 15 t tundish for casting 中120 mm pipe billet by horizontal continuous caster, the 1:1.5 water model system has been established to examine the flow field in local tundish and study the effect of flow control device on behavior of liquid flow in tundish. Results showed that the dead zone ratio in tundish obviously decreased by u- sing turbulence inhibitor, but it was limited to prolong the minimum residence time; the residence time of liquid steel in tundish obviously increased by using inlet launder and low dam to promote the inclusions floating.
